Answer:
b
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V =
πr³ ( where r is the radius )
Here r = 3, thus
V =
π × 3³
=
π × 27 = 4π × 9 = 36π in³ → b
Answer:
-13
Step-by-step explanation:
Opposite of 9t = -9t
Taking the sum of 9t - 13 and -9t
Sum = 9t - 13 + (-9t)
Sum = 9t - 13 - 9t
Sum = 9t-9t - 13
Sum = -13
Hence the expression in standard form is -13
